The speedometer only works when u speed up to 65 mph and then let off the gas. it only moves then drops back to zero. I drove about 100 miles and the trip went from 0.0 to 0.3 why?
your spedo is a bad sensor located on top of the rear axle your fuel gauge is a bad sending unit in the tank and the trip is integrated into the spedo. this is the most likely cause and i have replaced several.
